We have managed to get FFB on w/RF on w/xA taking 150uA. This is all without Feedforward, however. Finding that when engaging FF DAC, getting a 1C04H saturation fault.
First thing we did in attempts to rid ourselves of saturation faults was re-steer the 1C line horizontally such that the first ~6 correctors were zero'ed out. 1C04H included. Still getting saturation faults.
Looking at the FFT of the three horizontal BPMs in use, seeing some very strange signatures on the 1C07 (top in F1) and 1C16 (bottom in F1), but not on 1C12. 300Hz, 420Hz, and 660Hz?
